实验制备了结构为多层阳极/EHI608/NPB/Alq3:ELL/ETL1/LiF/Mg:Ag/CPL的硅基绿光有机电致发光 OLED器件，研究了不同掺杂浓度对器件驱动电压、亮度、发光效率和 EL光谱影响。在此基础上，通过在阴极上制备了一定厚度的阴极耦合层 CPL，并研究了阴极耦合层对 OLED器件微腔效应影响。结果表明，随着发光层掺杂浓度的增大，器件驱动电压、发光亮度和效率逐渐增加，并出现 EL光谱发光峰位红移。同时，随着 CPL厚度增加，多层膜系 ETL/EIL/Mg:Ag/CPL透过率逐渐增加，当阴极耦合层 CPL厚度在 30 nm时候，多层膜系结构的透过率和透过频带较高，多层膜系透过率光谱坐标接近白光(0.33,0.33)等能点。此时，顶发射绿光 OLED器件在不同视角下 EL光谱的蓝移现象最大限度得到了抑制，且 EL光谱半峰宽明显增加。

Green light devices with a top multilayer anode/EHI608/NPB/Alq3:ELL/ETL02/LiF/Mg:Ag/ out-capping layer configuration were experimentally prepared on silicon substrate.T he doping concentrations of emitting layer have strict effects on the driving voltages, luminances, efficiencies and electroluminescent(EL) spectra of OLED devices. Further, the microcavity characteristics of top-emitting green OLED devices were examined. Based on the transfer matrix theory and optical constants of materials, the transmission of multilayer thin films (ETL/EIL/Mg︰Ag/CPL) are numerically calculated with matlab program. The experimental results demonstrated that based on an increase in the dopant concentration of the guest materials, the electroluminescent (EL) efficiency, driving voltage and luminance of the organic light-emitting device increased. And the doped concentration of the guest is controlled at 3.5%, the efficiency of the device remained stable, the transmission of multilayer thin films (ETL/EIL/Mg︰Ag/ CPL) gradually increased, according to the increase in the CPL thickness of the cathode refractive index matching layers. When the CPL thickness is controlled at approximately 30 nm, the transmission in the entire visible range is maximized, and the transmission spectrum (CIEx, CIEy) value of multilayer thin films (ETL/EIL/Mg︰Ag/ CPL) are extremely near to the white equal energy (0.33, 0.33).项目、云南省技术创新人才培养项目（2017HB111）、云南省“万人计划”产业技术领军人才培养项目等资助。
